Technology | Transfer
How do cans get from one machine to another? As an integrated conveyor chain is discarded for many reasons a transfer unit has to fulfil this task - fast, reliably and in a compact design.
Separate conveyor chains prove to be economically useful. The conveyor chain of a washing machine, for example, has to be replaced regularly because it is exposed to chemical detergents, heat and moisture. Within an accumulator however, it has a relatively easy and long life.
To guarantee the automatic run of production, parts are transferred from one conveyor chain to the next - a challenging task.
In the TD 40 transfer unit the parts are first drawn off the chain pins and are transferred to a rotating drum with vacuum troughs. If vacuum is shortly interrupted the part falls into a second drum which is placed under the first one. There it is pushed on the chain pins of the following chain – transfer is completed.
The transfer on angled infeed or outfeed conveyors works without vacuum. Here the part is mechanically stripped off the chain pin or pushed on it.
